PsLyk9, PsPAL2 gene expression in pea roots on days 8 (A) and 16 ((B), left) after infection with phytopathogenic fungi F. culmorum. Weakly pathogenic Fc 891 and highly pathogenic Fc 334 strains were used for infection. As a control, non-infected plants were used. Disease symptoms were evaluated in points on day 16 ((B), right), when the signs of disease began to appear on pea plants. No visible signs of disease were found on day 8 after infection. Asterisks indicate statistically significant differences compared with control non-infected plants: *** p < 0.001, ** p < 0.01, * p < 0.05.
